Study of low-latitude ionosphere over Indian region using simultaneous algebraic reconstruction technique

Recognizing the advantages of simultaneous algebraic reconstruction technique (SART), it is applied to investigate the electron density distribution of low-latitude ionosphere. The total electron content data measured at three receivers in West Bengal, India, are used in this analysis. The efficiency of SART in the reconstruction of large scale ionospheric structure is addressed through reconstruction of ionization anomaly. Comparison with the model ionospheric data ensures the accuracy of the SART method for the reconstruction at low-latitude region. Also, a case study with different reconstruction geometry reveals the ability of fast convergence of simultaneous algebraic reconstruction algorithm irrespective of the geometry.
